Understanding Peripheral Neuropathy: Symptoms, Causes & Treatment

Peripheral neuropathy is damage to the nerves that carry signals between your brain and spinal cord and the rest of your body — most commonly the ones running down into your feet and hands. Because those nerves handle both sensation and movement signals, damage shows up as a strange mix of symptoms that can be hard to describe to someone who hasn't felt it.

What it actually feels like

Patients describe it differently depending on which nerve fibers are affected. The most common complaints I hear are burning that's worse at night, tingling or "pins and needles," numbness that makes it hard to feel the ground under your feet, and sharp, electric-shock-like pain that comes out of nowhere. Some people also notice increased sensitivity — even bedsheets touching their feet can be uncomfortable. None of these are "normal aging." They're signals that nerve tissue is under stress.

Why it happens

There isn't one single cause. Diabetes and prediabetes are the most common drivers we see, because elevated blood sugar directly damages small nerve fibers over time. But we also regularly find cases rooted in poor circulation, chronic inflammation, past chemotherapy, alcohol use, autoimmune conditions, and nutrient deficiencies. In a meaningful number of cases, more than one of these is happening at once — which is exactly why a real evaluation matters more than a quick guess.

Why "just manage the pain" isn't enough

The default approach in a lot of medicine is to prescribe something for the pain and move on. That can help someone get through a night's sleep, but it does nothing to address the nerve damage itself — and untreated, that damage tends to progress. Our approach starts with figuring out what's actually driving your particular case, then building a plan around that, not just the symptom.

Non-invasive treatment options that make a real difference

• Anodyne infrared therapy — increases circulation to damaged nerve tissue, supporting the body's own repair process.
• ReBuilder nerve stimulation — uses a specific electrical waveform designed to retrain damaged nerves rather than just numbing pain signals.
• Neurofeedback therapy — helps address how the nervous system processes and responds to pain signals over time.
• Targeted nutritional support — correcting deficiencies (B12 is a common one) that are actively contributing to nerve damage.

None of these are magic fixes on their own. They work because they're combined based on what your nerve scan actually shows — which is the whole point of starting there instead of guessing.
